A modified syringe collects samples of a fluid without removing volatile compounds by forming a vacuum within a sample collection vial. The system includes a plurality of chip components, such as transient suppression regulators, that are configured to include a transmission path that is routed through the chip component for transmission of any signal, for example, a signal from a communication bus of the microelectronic device. Additionally, the EGM signal is used to determine whether premature ventricular contractions cause phase reversals of the T-wave alternans. The system and method also display a first set of recommended actions, as a function of the initial problem, and receive an answer from the user to the at least one question.
